What WAN technology do UPC use?

    I am studying for the CCNA and currently studying WAN technologies.

    I have been burnt in the past with other certs in studying very old technologies (now you know how this works, but no-one uses it anymore).

    I don't need to know how it works, just what they use (ISDN, ATM etc), I can do the rest.

    Kai.

    Their consumer and SME access network is based on DOCSIS.

    However, my understanding is that they also deploy fiber and fixed wireless for business customers. I'm pretty confident most of their backbone network is fiber too.

    As a result, you probably want to look at OTN / WDM (for the fiber network) and 802.11* or mircrowave technology along with Ethernet, TDM or ATM.

    Really depends what layer of the OSI model you are looking at... DOCSIS straddles layer 1 and 2. Fiber (802.3ae for 10Gbps and 802.3ba for 40+ Gbps) is layer 1 with most providers sending layer 2 ethernet packet over the fiber.

    If you want a good starting off point, have a read through the info linked off http://en.wikipedia.org/wiki/OSI_model - if you look at the page for each layer you'll see some example protocols listed.

    I read up DOCSIS and a few youtube videos. Anything like this gets me excited at the prospect of working in a NOC. When you have studied for a position which now is hard to get into, it becomes something more. I would probably be the crazy guy drooling over a network cabinet.

    DOCSIS is not really mentioned to much when studying for the CCNA, but Frame-Relay, ATM and DSL is. I was trying to relate how my internet works in relation to one of those WAN protocols. DOCSIS should of got a better mention in the book to avoid the confusion.

    Thanks for the replies!
